Italy secured the top spot in Group E by virtue of Belgium's 3-0 win over Ireland on Saturday.
It's the first time since 2000 the Azzurri have won their group at the European Championship. In that year's tournament, they had the same group mates as this year's tournament and collected a full nine points. They defeated Romania and Netherlands in the knockout stage before falling to France, 2-1, in the final.
The Azzurri, with a full six points, enter the knockout stage with a tiebreaker over Belgium, who they defeated 2-0 in their tournament opener. They also defeated Sweden, 1-0, on Friday. Emanuele Giaccherini and Graziano Pelle both scored against the Red Devils, while Eder tallied the lone goal against Sweden.
They'll play their final game of the group stage against Ireland on Wednesday before facing the Group D runners-up in the quarterfinal round June 27 at Stade de France.
The two-time defending champions Spain currently lead Group D with a full six points after a 1-0 win over the Czech Republic and 3-0 victory against Turkey. They'll play second-place Croatia on Tuesday. Croatia beat Turkey, 1-0, but drew level with the Czechs, 2-2, to take four points entering their matchup against Spain.
The Azzurri won their last quarterfinal match in 2012 at the Euros with a 4-2 victory in penalty kicks over England.
